- Title
On the Mechanism of Electron Beam Generation in an Open Discharge with Anomalously High Efficiency.

- Abstract
The parameters of an open discharge operating without anode grid at elevated beam current densities are studied. It is demonstrated that the discharge is characterized by an almost 100% efficiency of electron beam generation in both pulsed and continuous regimes. A mechanism is proposed that accounts for such a high efficiency, according to which a zone of low potential gradient formed near the cathode blocks the ion current to cathode, while the electron emission proceeds by the photoemission mechanism.
